STEAM TRAP.

Patented May 24, 1887.

' UNITED STATES PATENT OFFICE it STEPHEN H. HOWLAND, OF SPRINGFIELD,MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO CHARLES E. BUELL, OF SAME PLACE.

STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 363,641, dated May 24-,1887. Application filed January 19,1887. Serial No. 224,817. (No model.)

To aZZ whom it may concern.

Be it known that I, STEPHEN H. HoWLAND, of Springfield, Hampden county,State of Massachusetts, have invented Improvements in SteamTraps, ofwhich the following is a specification.

My invention consists, primarily, in the combination, with a metal caseor shell having an outlet, of a cap or end therefor that is removablyattached thereto, and is provided with a filter-like adjunct, and withan induction and an eduction port, substantially as hereinafterdescribed. i

Figure 1 shows my invention in a side ele- I 5 vation in crosssection.Fig. 2 shows the filterlike adjunct. Fig. 3 is a view of the exterior ofa steanrtrap arranged according to my invention, and Fig. 4.- is adetailed part of the same.

Referring to Fig. 1, A is a cast-iron shell with one end sealed and itsopposite end open, and provided with a flange, the sealed-up end beingenlarged by swells to give space at desired poiuts,for purposes to bereferred to here- 2 5 inafter. The legs h and p are preferably cast withthe shell or body of the trap, but may be added thereto. The leg h ismade hollow, as shown, and is used as a water-way to draw oft the waterof condensation in the normal operation of the apparatus, and is tappedat points z and n to receive, respectively, the drip-cock i and awastewater pipe or conduit. By this arrangement the lever d, with itsfloat C, pivoted upon the drip'cock i, can be wholly within the shell orbody of the device, and

permit of the employment of the removablyattached end B, for otheradditional uses, with advantages not heretofore afforded.

The end B is of cast-iron, and is a flanged 4o chamber half cylindricalin shape, as shown in plan view in Fig. 4. This chamber is provided withapartition-like projectiomg, (shown in Fig. 1,) and to this and a slightinward projection on each side of the center at the bottom ofthe chamberisattaehed the brass filter-like adjunct f, which may be mounted upon acircular sheet of metal, that could be affixed to the partition-likeportions of the chamber B, or be held between the flanges of 5 thechamber B and the body A.

The filter f may extend to the bottom of chamber B, to allow of completedripping of the apparatus; but a like result is accomplished by leavinga slight space beneath the filterf, or the piece on which it is mounted,and the bottom of the chamber B.

The induction-port K at the top of chain ber B receives the inlet-pipefrom a system of steam-pipes, and the sediment from the said pipes isretained in the chamber B, while the water of condensation filters intothe shell or body A, and is trapped off by the rising of the float 0through the drip-cock 2', leg 71, and outlet a.

When it is desired to remove the accumulated sediment from the chamberB, -it can effectually be done by the removal of the plug normally inthe eduction port j, when the steam will blow out the sediment, thusavoiding the removal of the chamber B from the body A to removesediment, as in other steamtraps, the chamber B requiring to be removedonly to repair the float and dripeock, if that should become necessary.

A vent-cock is provided at m, to allow air to escape from the trap whendesired.

What I claim is-- 1. In a steam-trap, the combination, with the body ofa steam-trap, of a float-actuated cock wholly within said body, and achamber removably attached to said body that is'provided with aninduction and an eduction port, and a filter-like adjunct between saidbody and said chamber, the whole arranged and operating substantially asdescribed.

2. In a steamtrap, the combination, with the body of a steam-trap, of afloat-actuated cock having its outlet through a supportingleg of saidtrap, and a chamber removably attached to said body that is providedwith an induction and an eduction port, and a filterlike partitionbetween said body and said chamber, substantially as set forth.

3. In a steam-trap, the combination, with the body A, having one endscaled up, of a chamber removably attached to its opposite end, that isprovided with an induction and an eductiou port, and a filter-likepartition be tween said body A and said chamber.

4. In a steam trap, the combination of the following elements: the bodyA, the float (J, cock 2', the leg h, the chamber B, with filterf, andvent m, the whole arranged substantially as described.
